If you want a sketch with the wires in actual color, etc., try here; but it is much less detailed than my schematics, below.

For a .pdf of the below schematic for the R90S, R60S, R75/6, R90/6;  Click http://bmwmotorcycletech.info/R90S.pdf          
This is a HIGHLY USABLE VERSION

Below is the same schematic as above but in large .GIF format.  Larry Simko provided me the original artwork for the below sketches, for which I thank him, and I have left his name at the bottoms.    It will not appear to be very usable on a modest, even larger screen, as initially presented.    It should be expanded in your computer's imaging program as needed in order to see the fine details.    If you do not know how to do that, then use the above clickable .pdf version.  Some browsers allow you to expand the image, which may work fine and is easier to do, than use an imaging program.

Note that both the .GIF and the .PDF schematics have the corrected instrument cluster wiring diagram (some old BMW literature is wrong).  NOTE also that sometime in 1976, the wiring changed again, in some minor areas.

Just below this first sketch is a large .bmp version.
